Science
Mechanism of Action
This ingredient operates on multiple levels: as an emollient, it helps to fortify the skin's natural barrier, filling microscopic intercellular gaps to prevent trans-epidermal water loss and increase hydration. Concurrently, it acts as an emulsifier, expertly blending immiscible phases such as oil and water to create stable emulsions. Its mild surfactant properties further reduce surface tension within formulations, ensuring uniform consistency.
